Skill
Plans and Conducts Investigations
Child plans simple investigations, gathers the materials, carries out the steps, and records what happens.
Ages 36–66 months
Why it matters
Turning a wondering into a doable test is the engine of inquiry. When children decide what they want to find out, name the materials they will need, follow the steps in order, and record observations with pictures, marks, or simple graphs, they learn that questions can be answered through deliberate, organized action rather than guessing.
Builds toward this milestone
- plans and conducts investigations and experiments. — Head Start ELOF
What mastery looks like
- With support, names a testable question to explore, such as whether plants need water to grow.
- Gathers the materials and follows the steps of a simple investigation, with growing independence.
- Records data during the investigation using pictures, tally marks, or a simple group graph.
How to observe it
- Can the child say what they want to find out and which materials they will use?
- During the investigation, does the child carry out the steps in a sensible order?
- Does the child record what happens with marks, drawings, or photos?
Accessibility
- Offer picture step-cards so children can follow and order the procedure visually.
- Let children record data by placing stickers or stamps rather than only drawing or writing.
Safety
- Choose safe, non-toxic materials and supervise closely around water, soil, and small objects.
